[PATCH v3] remotes-hg: bugfix for fetching non local remotes

[Joern Hees <dev@joernhees.de>]

6796d49 introduced a bug by making shared_path == ".git/hg' which
will most likely exist already, causing a new remote never to be
cloned and subsequently causing hg.share to fail with error msg:
"mercurial.error.RepoError: repository .git/hg not found"

Changing shared_path to ".git/hg/.shared" will solve this problem
and create a shared local mercurial repository for non local remotes.
The initial dot circumvents a name clash problem should a remote be
called "shared".
